Be it known that l, SYDNEY ORMOND GoL- DAN, a citizen of the United States` residing at New York, county of New York, State of New York, yhaye invented certain new and useful Improvements in Inhalers; 4and I do hereby declare the following to be a full, clear,

as will enable others skilled in the art to which My invention relates'to apparatus for the and hasA for its .object to provide a simple,

employed 'toadminister anesthetics singly or in any desired relation either by the open My invention is illustrated in the accompanying drawings, in which-'V VFigure 1 is a general side elevation of the i Fig..2 is ailongitudina'l sectional view the various parts.4 -Fig. 3 is an enlarged crosssectionalview online 3 3, Fig. 2. Fig.4 is a perspective View of the removable basket for retaining the absorbent material that carries the liquid anesthetic; Fig..`5 is a perspective viewof the inhaler asarranged for the administratiou of chloroform or. similaranesthetic Fig. G is an arrangeether 'anaesthesia by theclosed method.

Referring to the drawings, the inhaler comprises a main casing 1, preferably formed-as a metal cylinder or tube, having secured at one end thereof a face-piece or hood 2. The

vided with recessed portions tow receive the chin and nose ofthe patient and a rim between the recesses to lie snugly against the faceand form an air-tight `joint. This facecured to the central 'cylinder or tube 1 by stretching the reinforced and constricted end of the face-pece overl the end flange of the cylinder, asshown in `l.iig.2. In lthe pr'eferred form of my device the tube comprises distal end of which telescopes a smaller cyl: inder 3. f These two cylindrical portions are provided with a series of circumferential perforations et and 5 in such` relation. that 55 they may all be turned out of registry withl each other or any number fromone to the entire series brought into registry to accom-` plish objects to be described later. I

Secured in the end of the smaller' cylinder 6o 3 is the flanged disk 9, provided with perforations 9, which serve to establish commucation through ther cylinder. Attached to disk 9, preferably by a central stud, is a rotary Valve 10, provided with perforations, 65 which are adapted to register with the corre-A sponding perforations in the disk 9. Said valve 10 is provided with an annular ilange which engages with the interior wall of the cylinder 3, to which iiange is attached an op 7o eratingLhandle 1l, extending through an elongated slot 12 in said cylinder 3, which slot determines the range of operation of the handle, and consequently the opened and closed position of the valve l0.

' Secured to the tlange 8 of the disk 9 is a cage or basket consisting of a ring 6, to which is attached a series of arched wires 7, which are united at their middle points to form a cage-like structure generally hemispherical 8o inform. This device is preferably arranged to project from the end of the short cylindersection, as indicated in Fig. 2.

Mounted Within the cylindrical section 3 iniclose proximity to the valve or obturator 85 is a removable cage or basket adapted to retain the absorbent material 15,whicl 1 receives the'liquid anesthetic. This cage or basket comprises a ring 13, which fits snuglywithin the end of the cylinder 3 and has attached 9oV thereto a series ot' intersecting arched wires 14, one end of each of which projects to constitute a `bent`spring and clutch Amember 14', all of which bear upon the interior surface ofA the cylinder 3 and serve to retain the cage or 95 basket in properposition.

Secured to the outer end of the'cylindrical ,section 3 by the usual flanges provided on the end thereof is a gas-bag 16, provided with a constricted neck 16', which constitutes a-n roo air-tight but readily-detachable connection between the cylinder 8. and the gas-bag 1'6.

At its opposite end said bag 16 is provided with a connection 17, having a cock 1S, which connection is adapted to establish communication between a source of gas and the bag 16. ln the form of my invention shown in Fig. 1 the pipe or connection 17 is in communication with a 19, which in turn is connected by two pipes and 21 to two reservoirs of gas, as will be explained later. This form of my apparatus is adapted for general use and'may be applied to administer an anesthetic either by the open 'or closed method for gas inhalation alone, for the administration of nitrous oxid and oxygen ether and nitrous oxid, chloroform, or any of the known anesthetics either singly or in combination with each other or with oxygen.

When the apparatus is to be used in gasinhalation alone, 'the operation is as follows: The gas-bag 16 is completely collapsed, therev -by forcing out all atmospheric air. The valve or obturator 10 is closed by revolving the handle 11 until it reaches the end'of the slot 12l opposite the point of said slot marked Open. The bag is then filled with gasi. e., nitrous oxid-and the inhaler applied to the face in the ordinary manner to avoid crevices through which air may enter. Obturator or valve 10 is then turned to open and the patient instructed to breathe in deeply. Gas anaesthesia will quickly result, and it is to be noted that as the ypatient is forced to breathe the mixture in the bag'repeatedly it may be found desirable to renew the gas iu the bagfrom time to time, which may be done by admitting a fresh charge by way of connection 17 and cock 18. This re- 1 charging of the bag should take place from time to time in order to keep it fairly well filled. Should i t be found desirable to admit air to the patient, the end cylinder 3 may be turned to bring one or more of the perfora- 'tions 4 5 into registry7 sothat a given quanvwhen the administration of gas may be continu-ed. Should it be desired to discontinue the flow of gas for a given time, the valve or obturator 10I is closed and the perforations 4 5 broughtv into registry to admit air. If more air is re uired after the five apertures are open, thesmaller cylinder is withdrawn from the larger until the series of lapertures 5 appear beyond the outer end of the longer cylinder, thus affording ten apertures through which air may enter. In administering oxygen in connection with gas the bag 16 is inliated -with a mixture of nitrous oxid and oxygen, which is admitted through the respective'pipes 20 and 21, which are in communication with reservoirs or receptacles holding the respective gases. After the bag has been inflated the cock 18 is closed as before andthe inhaler applied as above described. It is to be noted that in applying the nitrous oxid oxygen combination the oxygen-supply is regulated by the effect produced upon the patient and not by'any regulating device. If the administration of ether is to follow that of the gas, the operation is carried out as above described until the patient is anesthetized with gas. The small cylinder is then revolved within the large one until a single perforation 4 is brought into registry with a perforation 5,

pushing itwell forward toward the obturator, v

when the inhaler-is again applied. The patient thus breathes ether and gas, and should it be found necessary to ad mita breath or two of fresh air it may be supplied by revolvingA the inner cylinder to cause the perforations 4 5 to register, as before, or by tilting the inhaler away from the face. After anaesthesia is com plete the gas-bag may be removed from the cylinder and a thin rubber bag may be applied to the cylinder in lieu thereof, as shown in Fig. 6, into and from whichthe expirations and -inspirations of the patient are drawn. Thethin rubberbag is made of the fullest .respiratory capacity and especially thin, thereby serving'as an excellent respiratory index by its movement during inspiration and expiration. During inspiration insuiiiation of the gas-bag 16 or rubber bag 16" is prevented by the cage 7 in the end of the cylinder. Ether alone maybe administered by means of the inhaler, as arranged in Fig. 6, which figure represents theinhaler with the closed method; but in order to use it for the open method'the small cylinder 1', with the thin rubber bag 16l attached, is withdrawn.

When it is desired to produce anaesthesia by chloroform, the open method is employed, the gas-bag 16 is dispensedwith, and the absorbent 15 in the cage or basket within the cylinder is dropped with the anesthetic, and

the patient caused to breathe the same freely v through the open tube. In this method of application the apparatus may be arranged conveniently, asshown in Fig. 5, in lwhich the smallercylinder has secured to its outer end a hood or'face-piece 2, while the removable basketin the opposite end thereofis surrounded by a piece 'of absorbent cloth, which in turn is prepared with chloroform or equivalent anesthetic. f

When nitrous oxid alone is to be used, the Y-tube is .ietached,A and one piece of rubber tubingconnects-the gas-bag andthe cylinder `which the gasis stored; A j A- .j Itistobeparticular1y-noted`that the appatus"as thus 'describe'd is light,jdurable, hportablajand inexpensive, is simple in' con-V struction and. maybe readilyassembled or `1. taken`.apart for purposes fof aseptic treat-` `finencgand as it is capableof application in @the administration of` anesthetics by' any of the methods known in practice it is equally Well adapted` to the use of the practitioner whojadministers an anesthetic only occasion'- allyas well as in the hospital where the fre-` quent application ofkianesthetics under varyngconditionsand by all the known methods' 4is a `matter ofconstantpractice.
